system.println("vovel");
break;
case "a" or "A":
system.println("vovel");

If you need to switch over a value that is a string you can embed it into an Enum:

public class Example{
enum Values { a, b, c }
public static void main(String[] args) {
Values v = Values.a;

switch() {
case a:
//TODO
break;
case b:
//TODO
break;
case c:
//TODO
break;
}
}
}

since you are using characters try using ' ' (Single quotes) instead of using " " double quotes

You cannot use strings on Swithc, you can only use int. So, it would be a better idea to capture the lettes ascii code and evaluate your switch accordingly.

Im a new learner of java. This example of switch case helped me to understand the syntax clearly. The program also provided more knowledge. I will visit this site whenever i get doubt.Thanks. Good work.
